99 Marked Trumpet silver vase. 11” x 6. Nice patina and design.

This is a nice antique or vintage trumpet vase which is marked 99 on the bottom as you can see in the pics. Nice patina on it. Please comment if you know the origin of this vase as I tried to do a Google search and came up that it was 99 percent silver from Korea. Please comment if you think this is just plated. It doesn’t stick to a magnet. Sold as is. Offers welcome. Bundle with other items in my closet and save.
